My 4.5 month old has been doing unusual things lately, and I was wondering if any of you are experiencing these things. Not worried, just curious. Rolling her tongue over her gums (think she just discovered this), humming a LOT, trying to nurse while sticking her fingers in her mouth and tonight...blowing raspberries while nursing!!!! Milk and drool going everywhere. I didn't experience this with my DD1..well, except for trying to nurse with fingers in her mouth, too. Anyone else???
